Got this a week ago.  I was home one day on a day off. Earlier that day I could have sworn I saw nothing on my door and then a little later I found the sticker there.  I thought maybe I just didn't hear the doorbell, but other comments here reassure me of my first notion that they didn't really knock or ring the doorbell and had just left the yellow sticker.  I thought to myself "What package was I supposed to recieve?"  Then I looked at the sticker closely and realized there was no indication of who was trying to deliver this and also the sticker seemed generic in that it was prechecked for me to call their phone number.  The other two options were to redeliver on a certain date and the other was to pick up at the office.  What office!  There's no address or anything to identify where I would even pick it up if this option were checked.  I smelled BS.  I called the number and it rang for literally 2 minutes and then I hung up (you would think after a couple of rings you would get some sort of machine or a someone asking me if I could hold).  I then started to get the impression that this was not even a legitimate company but some loser living out of a trailer or his mom's basement that decided to try to pull a scam.  I wasn't completely correct but any business this unprofessional and deceitful should not receive any business.

A couple of suggestions to help your consumer affairs before you end up extinct.  Get voicemail and some sort of operating system to handle your phone calls.  Also, the idea of going door to door to sell your product is OK (as long as you have a permit to do so), but you should be upfront and tell people what it is consumers are calling on and not wasting their time with this BS.  You shouldn't say they had missed a package delivery when they aren't expecting anything (or maybe they are and you're wasting their time).  Plus if you're going to act like you are trying to deliver a package, you should at least try to see if someone would greet you at the front door.  And lastly, you and your employees need to learn how to deal with consumers.  You guys are blaming the them for being upset instead of looking in the mirror and seeing if maybe you are wrong for your marketing ploy.  Legal or not, this is shi**y consumer affairs.
